Piece of cake! All you need to do is throw money at the problem.
GM axles all use the same bolt pattern on the axle ends that allow you to bolt on any brake off any model of vehicle from any year so if you wanted to use late model Cadillac or Impala SS rear disc brakes hey would bolt on, same for the disc brakes off of the Firebird or the Camaro.
Wilwood built brakes for NASCAR starting originally with Girling calipers (just like Chevy did because they where the brakes commonly found surplus on WWII bomber and fighter aircraft). He then started casting his own calipers and disc rotors and machining them to his own specifications; which means that they will not interchange with anything else besides another Wilwood product, and there is no guarantee that it will interchange even then.
Wilwood sells brakes based upon the number of pistons and the thickness of the rotor. More pistons in the caliper yields a more even distribution of the clamping force for smoother stopping with less wear (an important consideration when brake pads frequently do not last an entire race). The thicker and larger the diameter of the rotor the greater the heat sink, and as such the less chance the brakes will fade. Down side of this is by increasing the unsprung weight it makes it harder to keep the tire patch flat on the pavement. This is why carbon fiber is replacing cast iron as a rotor material in racing, though there is a considerable difference in material price that prohibits there use on the street except in a very expensive sports car.
One final consideration (well two really)is that the brake assembly has to fit inside the wheel, and the front brakes must account for at least sixty percent of the car's stopping ability. So if you go huge by large on the rear brakes the front brakes must be even larger (and thus more expensive).
